Up to 50% of children with a genetic disorder unrelated to autism are mistakenly diagnosed with the developmental disorder, and that can lead to inappropriate treatments that can worsen their condition.

Genetic changes are almost certainly behind many cases of autism, and the latest research suggests that some of those alterations may be contributing to more densely connected networks of brain nerves.

Language can prove a bugaboo for children with autism. Now new research finds that it’s possible to use toddlers’ brain responses to words to predict their linguistic and cognitive skills down the road.
